Narrativa dei Caraibi nel nuovo millennio

2020

L’etichetta “Letterature franco-caraibica” utilizzata, per convenzione, dalla critica per indicare unitariamente la produzione letteraria in lingua francese della regione centrale del Continente americano è assai impropria. La regione dei Caraibi abbraccia, infatti, sia alcune delle isole dell’arcipelago delle Piccole Antille (Martinica, Guadalupa), sia l’isola di Haïti, che fa parte delle Grandi Antille, che la Guiana incastonata sulla costa orientale dell’America meridionale. Pur nella diversità dei movimenti ideologici e degli avvenimenti storici che si sono succeduti nella regione, le opere letterarie degli scrittori caraibici francofoni, nel loro insieme, hanno oscillato, e continuano …

The definition "Franco-Caribbean Literature" used by convention from the critique to indicate all the literary production in French of the central region of the American continent is very improper. The Caribbean region includes in fact the islands of Martinique Guadeloupe Haïti and the Guiana. Despite the diversity of ideological movements and historical events that took place in these countries the literary works of the Caribbean writers have fluctuated and continue to oscillate between two tendencies: that of rooting in tradition and that of escape from it. The writers show themselves open to comparison and dialogue with other literary and cultural traditions in order to create a narrative form that corresponds to the many inheritances of those composite populations. Here the cultural syncretism that has been created allows to recognize a common identity in the name of all that the West wanted to extinguish. The common denominator seems to be inverted in the contradictory result of courageous but dangerous encounters of curiosities that can lead to conflicts to exclusions.

Micropropagation of Genista aetnensis [(Raf. ex Biv.)DC]

2015

Genista aetnensis [(Raf. ex Biv.)DC] is a large deciduous shrub or small tree native to the Italian islands of Sardinia and Sicily. Being winter hardy and characterized by high plasticity in altitude and ecology, the species is grown in gardens and landscaping, both for flower and for its attractive shape. Genista species are generally propagate by seed or semi hardwood cuttings. In this report an efficient in vitro technique for propagation of G. aetnensis was investigated. Multiple shoots were induced on nodal segments of a mature plant of Genista aetnensis . The Murashige and Skoog medium, augmented with different concentrations of benzyladenine either singly or in combination with indol…

Micropropagation of Metrosideros excelsa

2008

Multiple shoots were induced on stem segments of a 8-year-old plant of Metrosideros excelsa Sol ex Gaertn. ‘Parnel’. Axillary shoots produced on uncontaminated explants were excised, segmented and recultured in the same medium to increase the stock of shoot cultures. The Murashige and Skoog (MS) medium, augmented with different concentrations of 2- isopenthenyladenine (2iP) and indole-3-acetic acid (IAA), either singly or in combinations, as potential medium for shoot multiplication by nodal segments was tested. In the following experiment equal molar concentrations of four cytokinins [2iP, kinetin, zeatin and N6-benzyladenine (BA)] in combination with equal molar concentrations of three au…

Improved micropropagation in Polygala myrtifolia

2004

Stem segments from apical shoot tips of Polygala myrtifolia were used as primary explants to establish in vitro cultures. Axillary shoots produced on noncontaminated explants were excised and recultured in the same medium to increase the stock of shoot cultures. Equal molar concentrations of five cytokinins 2-isopentenyladenine (2iP), kinetin, zeatin, N6-benzyladenine (BA) and adenine were tested for ability to induce axillary shoot development from double node stem segments. The highest rate of axillary shoot proliferation was induced on Murashige and Skoog agar medium supplemented with 1.8 M BA. Seven indole-3-acetic acid (IAA) concentrations (2.8, 5.7, 8.6, 11.4, 14.3, 17.1 M) were t…

Studi preliminari sulla propagazione gamica e vegetativa di Hypericum perforatum in ambiente mediterraneo

2014

La conoscenza dei fattori che influenzano la propagazione di una specie rappresenta un passo cruciale nella messa a punto di strategie per la sua moltiplicazione di massa e introduzione in coltura, sia in campo che in ambiente controllato. Sono stati approfonditi alcuni aspetti della propagazione gamica di Hypericum perforatum (di cui è nota la bassa germinabilità del seme), verificando in particolare gli effetti di variabili diverse (soddisfacimento delle esigenze in freddo, temperatura, substrato, presenza di PGPR, batteri promotori della crescita). Sono stati inoltre approfonditi gli studi sulle potenzialità di moltiplicazione vegetativa della specie, da proporre come possibile alternati…

Propagation of Artemisia Arborescens L. by stem-cutting: Adventitious root formation under different conditions

2012

Artemisia arborescens L. has gained a strong importance worldwide due to its many industrial uses and it has been recently considered as ornamental plant. A major constraint to its widespread cultivation is represented, by far, by the scarce availability of high-quality plant material for field establishment; hence, development of a fast and effective methods for its vegetative propagation is needed. An experiment was conducted to assess the effects of different harvest periods, NAA, and rooting substrates on rooting of stem cuttings of A. arborescens. Semi hardwood cuttings were collected from wild plants in February, April, and November. Half of the material was treated with 0.4% NAA and …

Justicia transicional y justicia reconstitutiva

2014

RESUMEN. El presente trabajo contrapone dos versiones de la justicia transicional: para la primera, minimalista, se trata de una justicia ordinaria que solo es excepcional porque debe ejercerse en condiciones extremas que no afectan sin embargo a su naturaleza. En cambio, en la segunda concepción, la justicia sale profundamente transformada ante el tipo de violencia política que debe afrontar, e inaugura de forma permanente una posición diferente de la justicia en la democracia. El sentido profundo de la institución de una nueva categoría de crimen, el crimen contra la humanidad, es esta exigencia de repensar el papel de la justicia asignándole la tarea de proteger la política de sus gérmen…

Comparing micro-cutting and mini-cutting technique for the clonal propagation of Metrosideros excelsa

2017

public gardens for its foliage and attractive red flowers. M. excelsa plants are commercially propagated by soft and semi-ripe cuttings. Therefore, new and more reliable propagation techniques derived both from conventional and advanced propagation methods should be considered to support Metrosideros nursery development. The mini-cutting and micro-cutting techniques were compared for the clonal propagation of M. excelsa. Ex vitro rooted micro-cuttings resulted superior to mini-cuttings in terms of rooting percentage, root number per cutting and root length by 23.5%, 42.5% and 2.4%, respectively. However, the mini-cutting technique can be considered an alternative reliable propagation method…
